How to Read “後悔先に立たず”
Koukai saki ni tatazu
Meaning of “後悔先に立たず”
“Regret does not stand ahead” means that regretting something after it has happened cannot serve as a substitute for advance measures or preparation.
In other words, even if you lament “I should have done this” or “I should have done that” after a failure or problem occurs, those feelings of regret cannot turn back time or change what has already happened. This proverb is used to emphasize the importance of advance preparation and careful judgment.
In daily life, this expression fits perfectly when you get bad grades after neglecting to study for an exam, when you forget an important appointment, or when you fall ill due to poor health management. Even if you think afterward “I should have studied more,” “I should have written it in my planner,” or “I should have lived more regularly,” it’s already too late at that point.
The reason for using this proverb is as a warning not to repeat the same mistakes, and to remind ourselves and others of the importance of being prepared in advance.
Origin and Etymology
“Regret does not stand ahead” has been established as a didactic proverb passed down in Japan since ancient times, but its exact origins are unclear. However, looking at the structure of this expression, it clearly shows the characteristics of classical Japanese phrasing.
The expression “saki ni tatazu” (does not stand ahead) was used in classical Japanese to mean “not useful in advance” or “of no help beforehand.” Unlike the modern usage of “tatsu” (to stand), here “tatsu” means “to be useful” or “to be effective.”
This proverb became widely known largely because it was frequently quoted in moral instruction books during the Edo period. In popular education of that time, such easy-to-understand expressions were valued when teaching the importance of preventing failures before they occurred.
It’s also thought that the concept of “regret” itself was influenced by Buddhist thought. In Buddhism, correcting present actions is considered more important than lamenting past deeds, and such philosophical background may have supported the spread of this proverb. The sound of the words is also easy to remember, and it became deeply engraved in people’s hearts as a moral lesson.
Interesting Facts
The word “regret” originally comes from the Buddhist term “koukai sange” (regret and repentance), and carried a deeper meaning of reflection and repentance than the modern sense of simply “feeling sorry.”
Among Edo period merchants, this proverb seems to have been particularly valued as a business principle. This is because regretting after neglecting to investigate a business partner’s creditworthiness or misreading market trends would be pointless once losses had already occurred.
Usage Examples
- I wish I had taken job hunting more seriously back then, but regret does not stand ahead
- Even if I think I should have gotten a health checkup, regret does not stand ahead, so let’s start with what I can do now
Modern Interpretation
In modern society, “Regret does not stand ahead” has taken on new meaning, especially in our information age where speed is valued. Inappropriate posts on social media, handling of personal information online, management of digital assets—once information is released on the internet, it becomes extremely difficult to completely delete in our current era.
In the world of investment and business, the importance of this proverb has also increased. Cryptocurrency crashes, sudden changes in stock markets, delays in responding to new technologies—in our rapidly changing modern world, there are many cases where the approach of “dealing with it later” simply doesn’t work.
On the other hand, modern society also values the concepts of “learning from failure” and “trial and error,” and there are increasing situations where learning from failures is considered more important than completely avoiding regret. Particularly in startup culture, the philosophy of “fail fast and learn fast” has become mainstream.
Additionally, modern people live amid information overload, making it nearly impossible to predict all risks in advance. Therefore, this proverb is now often used in contexts that emphasize the importance of “minimum necessary preparation” rather than “perfect preparation.”
When AI Hears This
The human brain is designed to place abnormal emphasis on “now.” Behavioral economics has proven that many people choose 8,000 yen today over 10,000 yen a year from now. This is a cognitive quirk called “present bias.”
What’s fascinating is that when this bias combines with the physical properties of time, regret inevitably emerges. Time flows in only one direction. In other words, the results of decisions made under present bias can never be undone due to physical laws.
Take exam preparation, for example. The brain overvalues “the fun of playing now” and undervalues “the joy of passing six months later.” But when exam day arrives, time cannot be rewound. At this moment, people first realize their error in judgment.
Even more surprising is that the brain experiencing regret is still controlled by the same bias. When thinking “if only I had done that back then,” people ignore the information and emotions their past selves possessed, evaluating the past with present knowledge instead.
In other words, “regret comes too late” represents an unavoidable phenomenon for humans, created by the structural characteristic of the brain called present bias and the physical law of time’s irreversibility. This proverb is an observation that captures the fundamental limitations of the human cognitive system with remarkable accuracy.
Lessons for Today
What “Regret does not stand ahead” teaches modern people is not to aim for perfection, but the importance of “doing the best preparation possible now.” While it’s impossible to predict all risks, it’s important not to neglect preparation within the range we can anticipate.
This proverb teaches us the importance of taking “one breath” before acting. Checking before sending emails, consulting before making important decisions, daily attention to health management—small considerations can prevent major regrets.
Also, in modern society, the importance of information gathering has increased. When making important life choices such as investment decisions, career changes, or relationships, we’re required to make judgments based not just on emotions but on sufficient information.
And above all, this proverb teaches us to cherish “this very moment.” We cannot change the past, but we can change the future depending on our actions now. Rather than becoming unable to act due to excessive fear of regret, we should move forward with challenges after making appropriate preparations. Perhaps acquiring this kind of balanced perspective is what we who live in modern times need.
